Software Development Engineer in Test (SDET)

Emergent builds autonomous coding agents that replace traditional software development by generating, testing, and deploying production applications directly from plain-language intent. Our systems run in production at global scale and are used to build millions of real applications.

Since our public launch, we've crossed $130M in Annualised Revenue and grown to over 10M users across 190+ countries, who have built 12M+ applications on Emergent. We're backed by Creaegis, Khosla Ventures, SoftBank, Lightspeed, Together, Y Combinator, Google, Claypond and Sentinel Global.

We're solving the hard part of AI-driven software creation: correctness, reliability, security, and scale in real production systems. The team is built by repeat founders, Olympiad medalists, IIT & IIM alumni, and leaders from Google, Amazon, and Dropbox.

We're hiring builders who want ownership, speed, and impact at global scale.

• →Design, develop, and maintain automated tests for web applications, APIs, and end-to-end user journeys.
• →Build reusable automation frameworks, utilities, and test infrastructure that scale with product complexity.
• →Develop and maintain UI automation using Playwright or similar modern automation frameworks.
• →Write automated API and integration tests covering functional behavior, error scenarios, and edge cases.
• →Integrate automated tests into CI/CD pipelines and improve execution speed, reliability, and feedback time.
• →Identify product risks early and work with developers and product managers to improve testability and prevent defects.
• →Investigate test failures, perform root cause analysis, and improve automation stability.
• →Use AI-assisted development and testing tools to improve test creation, debugging, coverage, and maintenance.
• →Test AI-powered product workflows, including dynamic UI behavior, generated outputs, failure scenarios, and regression risks.
• →Take end-to-end ownership of quality for assigned features, from requirement analysis to release validation.
• →Track automation coverage, defect trends, and test reliability to continuously improve quality.

• 3–6 years of experience in software testing, test automation, or SDET roles.
• Strong programming skills in Python or TypeScript.
• Hands-on experience with Playwright, or an equivalent browser automation framework.
• Good understanding of API testing, REST, HTTP, JSON, authentication, and integration testing.
• Experience with Git, CI/CD pipelines, and automated test execution.
